Technical Field
At least one embodiment of the present disclosure relates to a double-reamer symmetric dredging vessel.
Background
Typical dredging vessels today are: grab bucket type dredging ships, common cutter suction type dredging ships and bucket wheel type dredging ships. The grab dredger has poor sensitivity to extremely soft bottom mud, and is easy to generate the condition of digging harder stratum earthwork at the lower part of the riverbed during excavation, thereby leaking a large amount of surface layer bottom mud, particularly floating mud. The ordinary cutter-suction dredger is easy to cause the diffusion of pollutants in bottom mud, and can cause a serious back-silting phenomenon. The bucket-wheel type dredging ship can generate a large amount of pollutant diffusion in the dredging engineering, the dredging and back-dredging conditions are serious, the sludge removal rate is about 50%, the dredging is not thorough enough, and the large-area water body pollution is easily caused. These can greatly affect the efficiency and quality of the sludge cleaning.
